There are several new upgrades to the site. New and expanded summary
plots are available on the plots
page. The table now includes planetary
mass and radius. All calculations have been revised using the updated
HZ boundaries
of Kopparapu et al. 2014, ApJ, 787, L29.

The Habitable Zones have been expanded to include optimistic
boundary conditions (shown in dark green) which account for
the "Recent Venus" and "Early Mars" scenarios described by
Kopparapu et al. See
the About page for more details.
